I obtained my PhD in theoretical physics from Ecole Normale Supérieure in Paris and subsequently worked for three years as a postdoctoral researcher at the Max Planck Institute for physics in Munich before joining the Theory Unit at CERN in September 2014. My research focuses on understanding physics at high energies, including regimes where quantum gravity effects become important. In particular, my work aspires to obtain a deeper understanding of string theory, its relations to gauge theory and its implications for cosmology and phenomenology. A very challenging problem that my current work aims to address is to obtain a better handle on mechanisms for breaking supersymmetry in string theory and their consequences for Beyond the Standard Model phenomenology.
